Thanks!!
While the resource I checked (something-fishy.org) specifically lists "refusal to maintain a healthy body weight, or is at 85% of the recommended weight for their age and height", the site does specifically say:
"A sufferer DOES NOT need to appear underweight or even "average" to suffer ANY of these signs and symptoms. Many men and women with Eating Disorders appear NOT to be underweight... it does not mean they suffer less or are in any less danger."
You could get into a discussion about whether or not it's technically anorexia, but at the very least, it's EDNOS (eating disorder, not otherwise specified), and is very unhealthy and damaging behavior.
technically, anorexic just means emaciated, wasted away, extreme thinness -- it's the 'nervosa' part that brings the eating disorder into it
a person can be overweight and have an eating disorder, or they might just have disordered eating... or maybe they just don't have good information to go on
Anyway, here is a calculator with lots of information including calorie information for teenagers.

It can definitely happen if the body goes into "starvation mode" where it kinda realizes it's not getting enough calories so instead of burning existing fat, it conserves energy by slowing down the metabolism.
If you have the patience, this is a great article that explains it very well.
Skip down to the "Why is she not Losing Weight" section - it's about a page length down.
According to the DSM-IV to meet the diagnosis for anorexia nervosa you have to:-
- Have a BMI of less than 17.5, failiure to maintain 15% of bodyweight
- Missed 3 consecutive periods
Now that's not to say she doesn't have an eating disorder, she could be ED-NOS or a subclinical anorexic (not meeting the diagnostic criteria for anorexia nervosa)
